Security Flaw in Remote Desktop

March 13, 2012 1 comment

3/16/2012 UPDATE:

Exploit code published for RDP worm hole

————————————-

I don’t always post on Windows security updates, but when I do, it’s a Dos Equis near to my heart!  Do you use Remote Desktop?  Of course you do.  That’s why you need to install this update immediately:

MS12-020: Vulnerabilities in Remote Desktop could allow remote code execution

This is important for anyone running just about any version of Windows, but especially if you’ve got any machine exposing Remote Desktop directly to the internet (such as a Terminal Server).  Fortunately there is a mitigation for those who just cannot patch tonight: enable NLA for your Remote Desktop connections.RDP - Network Level Authentication

Hop to it!  Microsoft says not to wait for a normal patch-cycle on this one…

Talking IRM on RunAS Radio

April 28, 2011 Leave a comment

Recently, I had a chance to chat with Richard Campbell and Greg Hughes on the popular RunAS Radio Show.  The topic was Information Rights Management and how it relates to Exchange Server.  This was also a feature I demonstrated on stage at the Exchange Connections event in Orlando earlier this year. 

If you’re not sure what IRM is or does, or if you wish to learn more about it, be sure to tune in on May 4th to listen to show #210!

Major PKI Breach

March 23, 2011 Leave a comment

There has been a security breach identified with many Comodo Certificates. 

Comodo CEO Melih Abdulhayoglu calls the breach the certificate authority’s version of the September 11th terror attacks!

 

If you’re running Windows you need to apply this patch immediately.

If you’re using Mac or Linux, this affects you too, however I do not have links for you at this time.

Service Pack 1 for Windows 2008 R2 Now Available for Download

February 16, 2011 1 comment

Just a quick note to remind everyone that Service Pack 1 for Windows 7 and Windows 2008 R2 has just now become available for download on TechNet & MSDN.

If you don’t have a TechNet or MSDN subscription you should see it on the Microsoft Download sites next Tuesday. [EDIT: Here is the download Link]

Be sure to check with each product group before installing this.  Obviously it is supported with the OS itself (clustering, Hyper-V, RDS, etc) but you should seek a direct support statement like the one the Exchange group published.

You should also validate your 3rd party applications.  You’ll note there may be some issues with VMware, for example…

For more information such as release notes or articles on what’s new, visit this page:

Windows Server 2008 R2 Service Pack 1

Finally, here is a screenshot:

Installing and Using Forefront Protection Server Management Console 2010 – Part 2

December 12, 2010 1 comment

In a previous post, we took a look at Microsoft’s Forefront product line and saw where the new server management tool: Forefront Protection Server Management Console (FPSMC) fit in.  In this article, we will install FPSMC.

Before we start clicking, I’d like to point out a few important notes:

  • FPSMC cannot be deployed on a domain controller, an FPE server or an FPSP server.
  • FPSMC will not install on a server running any other Forefront product.
  • FPSMC will only support FPE and FPSP. It will not manage Forefront Security for Exchange server v10.x, Forefront Security for SharePoint v10.x and Antigen for Exchange and SMPT v9.x products – these still require Forefront Server Security Management Console (FSSMC).
  • FPSMC cannot redistribute the Cloudmark micro-updates.
  • FPSMC Beta will only support up to 100 servers per management console deployment.
  • FPSMC UI requires JavaScript to be enabled.
  • FPSMC must be installed on a domain-joined server.
  • FPSMC will not install on a server running any version of Microsoft Exchange Server or Microsoft SharePoint Server.

As well as some system requirements:

  • Windows Server 2008 R2
  • 300MB free RAM
  • 30MB free disk space (for the console)
  • 900MB free disk space (for SQL)
  • 4GB free disk space (for signature distribution)
  • .Net Framework 3.5 SP1 or later
  • Microsoft Chart Controls for Microsoft .NET Framework 3.5
  • IIS (for subcomponents visit TechNet)
  • SQL Express installs by default, but a licensed version of SQL recommended

You’ll also want to create a service account for the encryption of data between primary and backup servers.

Once you’ve got the above prerequisites in place, you’ll run the setup file and complete the product installation.  In the below demonstration, I did not deploy a SQL server, so the installer configured SQL 2008 Express on my behalf.  Additionally, if you do not have the Chart Control component listed above, you’ll be given a link to go get it.

Here are the installation screenshots:

Once the installation has completed, a program shortcut will be placed in the Start menu’s program list.  You can launch FPSMC from here, or directly via the following hyperlink:

Network Monitor 3x “How To” Videos

November 22, 2010 1 comment

I try to avoid reposting other people’s blog articles, as I am a man of efficiency and do not appreciate the extra clutter on the internet.  Smile  However sometimes I cannot resist!

In a previous post, I claimed Microsoft’s Network Monitor was my favorite protocol analyzer.  Recently I learned about a site with several instructional videos on this product; which is good, because using a protocol analyzer is anything but intuitive!

Apparently some of the videos date back to the ancient times of 2008, but there are fresh ones included as well:

  • Network Monitor Overview
  • Introduction to Capturing with Network Monitor
  • Introduction to Capturing Traffic using the command line utility NMCap
  • Tour of the NM3 Capture Tab
  • Tour of the NM3 Start Page and Parsers Tab
  • Introduction to basic filtering with NM3
  • Using the conversation tree with NM3
  • Introduction to using reassembly with NM3
  • Plugfest Intro To Network Monitor 3.3
  • Network Monitor Automation/Scripting using PowerShell

Installing and Using Forefront Protection Server Management Console 2010

November 21, 2010 1 comment

Do you use Forefront products to protect your Exchange or SharePoint environment?  Do you have more than one server that you’d like to manage centrally?

If your answer is “yes” to both of those questions, this post is for you!  In this multi-part article, I’ll show you how to install and use Microsoft’s latest (free) Forefront management product:

Forefront Protection Server Management Console (FPSMC) 2010 (Release Candidate)

However, before we start, I’d like to provide you with some Forefront orientation.  It seems that title “Forefront” is starting to mean so many things these days.  Hopefully this table will help put some of the product names into perspective:image

(Online services not listed)

That’s quite the moving target for us trying to learn!!

As you can see FPSMC has had a few different names so far.  In fact, Microsoft was going to release this as “Forefront Protection Manager”.  Talk about an identity crisis!

Now, if you are familiar with the existing Forefront Server Security Management Console (FSSMC) product, take a moment to note the differences between it and the new FPSMC:

So now that you have some background, let’s get on with it, shall we?

As I suggested above, FPSMC is a product we’d install to centralize our management of Forefront Protection 2010 for Exchange Server and SharePoint.  It does this through a web-interface, SQL and FPSMC agents running on each Forefront-protected server.

For a brief intro on the console, read this help article excerpt:

…[FPSMC] deployment allows administrators to deploy various files and settings to all or selected servers in the enterprise. Using the FPSMC, you can deploy the following to remote servers:

  • FPE and FPSP service packs and patches
  • Policies for configuration management
  • Forefront Protection product activation keys
  • Scan engine signature file updates (to centralize the update procedure)
  • Jobs that send reports on a fixed schedule

In addition, you can retrieve the following from remote servers:

  • Quarantined data.
  • Centralized reporting allows administrators to more closely monitor the servers in the enterprise and evaluate the effectiveness of antivirus software. The FPSMC collects statistics from all of its managed servers and stores them in a central repository for later analysis. Reports provide information about the trends in virus, filter, and update activity for each individual server or the entire enterprise.

Data retrieved by FPSMC will be stored in Microsoft SQL Server®. It can be stored in SQL Server 2008 Express Edition, which is a version of SQL Server with limited features. Alternately, data can also be stored on an existing Enterprise SQL Server 2008—locally or remotely—using SQL or Microsoft Windows® authentication.

In addition to the help article, here are some additional published resources on this product:

    While we’re on the topic of centralized Forefront Server Protection management, I’d like to point out that while we wait for this FPSMC Release Candidate to go Gold, you can manage your multi-server deployment with these scripts:

http://blogs.technet.com/b/fss/archive/2010/08/09/microsoft-forefront-protection-server-script-kit-now-available-for-download.aspx

We’ll compare the scripts to the new FPSMC product later in this article.

In the next part of this article, we’ll identify the prerequisites for FPSMC and begin our installation.
